Wilwood Left Black Aero6 Caliper, 1.62/1.12/1.12-Inch Stainless Bores

Wilwood’s black left AERO6 provides a six-piston differential arrangement in a forged radial housing. Each side has one 1.62-inch bore and two 1.12-inch bores, and internal ports replace an external fluid crossover tube. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. The company makes and designs disc brake components and systems for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Match the intended master-cylinder volume to this piston layout. Check a 12.19–15.00-inch rotor diameter, nominal 1.25-inch width and the correct 7.09-inch radial attachment before confirming wheel fit.

Ask PMB Performance to check the complete brake arrangement before ordering. Our team brings over 20 years of experience; photographs and measured bracket and rotor dimensions make that check more useful.
